MANUFACTURE OF PANELS, SLABS, AND OTHER ARTICLES FROM OXIDIZED OIL.

SPECIFICATION forming part of Letters Patent No. 249,428, dated November 8, 1881.

Application filed July 26, 1881. (Specimens.) Patented in England July 19, 1880.

I To all whom it may concern.-

Be it known that I, Fannnarcx WALTON, a subjectof the Queen of Great Britain, residing at Heatham House, Twickenham, in the county of Middlesex, England, have invented a certain Improvement in the Manufacture of Panels, Slabs, and other Articles from Oxidized Oil, (for which I have received Letters Patent in England, No. 2,975, dated the 19th day of July, 1880;) and I do hereby declare thatthe following is a full, clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same. I

This invention has for its object novel or improved applications of oxidized-oil or solidifiedoil compositions to panels, moldings, and articles requiring animpermeable molded surface. According to my invention Iapply or make use of oxidized or solidified oil compositions to give an ornamental or smooth, impermeable, and durable molded surface to panels or moldings for furniture, and panels or slabs to form ornamental parts of writing-desks, boxes, and such like articles; and I produce ornamental slabs or sheets for the decoration of shops, and for the exhibitionof maps or advertisements I in a decorative form, and ornamental letters and signs for shop-windows and the like. For the purpose of applying the oxidized or solidified oil composition I employ engraved metal dies or rollers.

A suitable composition maybe prepared as follows: A cement is first made consisting of oxidized oil, four hundred-weight; kauri gum, twenty-one pounds; resin, onehundred-weight. These materials are mixed in steam -heated pans.

The composition for molding consists of coment, (as above,) forty-eight pounds; wood fiber, forty-eight pounds; white lead, six pounds yvenetian red, three pounds. 'These materials are combined in radial mixing-machines. The color can be altered to suit the purpose required.

The composition is applied to the panel or article when in a plastic state, and considerable pressure is employed. Afterward the articles are hardened off by exposure to a moderate heat for a considerable time. The panels, slabs, moldings, ornamental letters, or like articles for receiving the impermeable molded eases other hard and solid materials may be conveniently employed. In this way, also, I coat. or surface articles requiring protection from moisture or the weather. Thus wheels are sometimes made. with the central portion of compressed paper; jection to which such wheels are liable is that the block is not impermeable. This objection I wholly remove by the application, as above described, by means ofdies and pressure, of a skin or surface of oxidized or solidified oil composition. The said composition in a plastic state is molded onto the block and in such a manner as to completely inease it, so as to exclude the terial. Other perishable articles liable to be injured by moisture may be similarly protected. Thus cords of fibrous material may be inclosed in an impermeable sheath. Where desired, ornamen ts may be produced upon the surface by means of dies or rollers at the same time that the impermeable skin or surface is molded upon it or subsequently.

Having thus described the nature of my said invention and the manner of performing the same, I would have it understood that Iclaim- Witnesses JOHN DEAN, J. WATT,
